This free tutorial will show you how to make many-(8 )-1/2 square triangle units like the ones above all at once. You can use these to make pinwheel/windmill blocks or any block involving a 1/2 square triangle
To make a Magic 8, first determine what size finished half-square triangles are desired.
Determine your 2 fabrics, mine are lime green and white
With right sides together, draw two diagonal lines corner to corner.
Stitch a quarter inch of either side of both drawn lines.
Carefully cut apart with out shifting the stitched fabric square.
There will be four cuts:
Cut down the centre vertically, horizontally and then diagonally on each line you drew earlier
Use a rotary cutter and ruler to make sure you are accurate
Separate all 8 units and you will see you have 8- 1/2 square triangle units made like magic!
Press towards the dark fabric and sew together like the below graphic and use pins to match points (recommended)
Press connecting seams open to avoid bulking up the centre seam (recommended)
Admire your efforts- I think this is the easiest way to make 1/2 square triangles!
Now get busy and make a quilt entirely from the method above with pinwheels/windmill blocks LOL.
It would make a great summer quilt, don't you think?
